PLOW ATTACl-llVllEN'l.

- srEcIrIoA'rIon forming part at meets .latent No. 655,870, dated Au er. 14.,1eoo. Application filed November 21}, 1899. $erial1lo. 738,189. (No model.)

Island, in the county of Rock Island and State of Illinois, have invented a new and useful PlowAttachment, of which the following is a specification.

One of the great objections to nearly all plows now in use and one of the principal disadvantages arising from the necessary employment of moldboards resides in the fact that there is a side thrust on the machine, brought about bythe action of the moldboard upon the soil, which causes the machine to sheer off to one side as it is drawn through the field.

The chief aim of the present invention is to overcome the objection above noted by providing a guide-cutter which is adjustable up and down and also capable of being adjusted as to its angle with respect to the line of movement of the machine. As a result of this the direction of movement of the plow is altered, or, in other words, the plow is enconnection with plows of different construe.

tions and having moldboards of different pitch and therefore tending to crowd the plow to a greater or less extent to one side.

Another feature of the invention resides in the fact that the guide-cutter may be depressed to the full depth of the plow, so that the latter can move in or out when a sudden jerk of the team is imparted to the plow. The

plow isthus enabled to run with greater smoothness and steadiness.

The detailed objects and advantages of the invention willappear in the course of the ensuing description.

The invention consists in certain novel fea turesand details of construction and arrangement of parts, as hereinafter fully described, illustrated in the drawings, and incorporated in the claims.

In the accompanying drawings, Figure 1 is a plan view of aplow, showing the guide-cutter applied thereto. Fig. 2 is a side elevation of the same. Fig. 3 is a rear elevation. Fig. 4c is an enlarged detail section taken longitudinally of the cutter-axle spindle. detail perspective View of the bracket.

Similar numerals of reference designate corresponding parts in all the figures of the drawmgs.

Fig. 5 is a 1 Whilethis invention is applicable to both single sulky plows'and gang-plows and the like, for the' purpose of illustration I have shown the guide-cutter and its attachments V In carrying out the present invention I employ a bracket 5, which is bolted, as at 6, to one of the plow-beams and whichis bifurcated to form an upper arm 7 and a lower arm 8, the said arms being provided with bearing-sleeves 9, in which is journaled the vertical spindle 10 at the forward end of a caster-wheel arm or frame 11, forked to receive the caster-wheel 12, which is journaled therein and trails behind the machine. The upper arm '7 of the bracket 5 isextended to form a horizontal plate or rest 13, provided at one end or side with an openinglet and at the opposite end or side with a slot 15,which is described on the arc of a circle of which the opening 14 is a center,

The cutter-axle is shown at 16 and is journaledin bearings 17 and 18, each of which has a downwardly-extending stem 19. The stem of the bearing 17 passes through the hole 14 ing 18 may be adjusted backward or forward for changing the angle of the cutter-axle, and consequently the angle of the guide-cutter, which is mounted thereon. After the adj ustment has been efiected and the cutter brought to the desired angle by tightening the nut the parts are held in fixed relation to the bracket and the guide-cutter is prevented from changing its angle.

The outer end of the cutter-axle 16 is extended in the form of a crank-arm 21 and its outer end is reduced to form aspindle 22,upon which is journaled a rotary guide-cutter 23, having a sharpened cutting edge 2i. Mounted upon the inner end of the spindle and hearing against an annular shoulder 25 thereon is a sleeve or collar 26, in which one of the hub ends 27 is received and housed. The said hub end is provided with an annular groove 28, which forms a receptacle for sand, dirt, and other foreign matter, and the sleeve or collar 26. is provided in its bottom with a dischargeopening 29, through which the dirt, 650., may pass as it falls from the hub of the cutter. A similar sleeve or collar 30 is secured upon the outer end of the spindle by means of the usual spindle-nut 31 and incloses the outer end of the hub, which is grooved similarly to the other end, the collar 30 being also provided with a discharge-opening 32 for the same purpose as the opening 29. By this means any sand, dirt, or other foreign matter which may fall upon the hub of the cutter will be prevented from getting upon the spindle on which the cutter is mounted.

The bearing l8is of greater height than the bearing 17 in order to enable a latch-lever 33 to be fulcrumed thereon, as shown at 34. The lever 33 is provided with a toothed segment 35, which meshes with a spur-wheel or pinion 36, fast on one end of the cutter axle 16'. The bearing 18 is also provided at its top with a notched segment or rack 37, with which a spring-actuated latch 38 on the lever 33 engages for holding the lever in any adjusted position, the latch being operated by the usual thumb piece 39. The operator by throwing the lever rearward may rock the cutter-axle 16 and lift the guide-cutter 33 out of the ground for the purpose of turning a corner or when the machine is not in use. By

. throwing the'lever forward he may depress the guide-cutter to any desired extent to enable it to obtain the necessary hold upon the ground and to obtain the required bracing effect of the guide-cutter on the machine.

The plate or rest 13 is provided with a downwardly-extendin g brace-ear 4.0, which is adapted to be bolted, as at 41, to the moldboard of acts asfa guide for the machine to properly space the furrows, but by reason of its angular disposition it acts to counteract the tendcutter with respect to the path of movement of the machine said cutter may be used in connection with plows of different constructions and equipped with moldboards of dif ferent pitch.

The rotary cutter is especially useful as a colter when associated with a gang-plow, such as illustrated in the drawings, and when thus used the said cutter performs the function of a rolling colter for the first and outermost plow. In this connection it will be understood by those familiar with the art that on the first round the first or outermost plow would have no colter cooperating therewith, but after this first round the cutter 23 would act in this capacity, in combination with the said plow.

From the foregoing it is thought that the construction, operation, and many advantages of the herein-described invention will be apparent to those skilled in the art without further description, and it will be understood that various changes in the sire, shape, proportion, and minor details of construction may be resorted to without departing from the spirit or sacrificin g any of the advantages of the invention.

Having thus described the invention, what is claimed, and desired to be secured by Let= ters Patent, is-- I 1. In a plow attachment, the combination with the machine-frame carrying the plow or plows, of a rotary guide-cutter arranged at one side of the path of the plow or plows, means for setting and holding the cutterat an angle to the plane of movement of the machine-frame, and means for adjusting the cutter in a vertical direction, substantially as described.

2. In a plow attachment, the combination with the machine-frame carrying the plow or plows, of a rotary guide-cutter arranged at one side of the path of the plow or plows, and beyond the landside portion or portions thereof, and means for setting and holding the cutter at an angle to the plane of movement of the machine-frame, substantially as described.

3. The combination with the machineframe, of a guide-cutter, an axle for the cut ter, and bearings for said axle, one of the bearings being swiveled and the other bodily adjustable, whereby the angle of the cutter with respect to the path of movement of the machine may be adjusted and the adjustment maintained, substantially as specified.

4. The combination with the machineframe, of a guide-cutter, an axle for the cutter having a crank-arm on which the cutter is journaled, bearings for said axle, one of which is swiveled and the other bodily adjustable, and means for rocking said axle, substantially as described.

5. The combination with the machineframe, of a guide-cutter, an axle for the cutter having a crank-arm extension on which the cutter is journaled, bearings for said axle one of which is swiveled and the other bodily adjustable, and an operating-leverfulcrumed on one of said bearings, substantially as and for the purpose specified.

6. The combination with the machineframe, of a guide-cutter, an axle for the cutter, a bracket having a slot, a bearing having a swiveled connection with said bracket, a second bearing having a stem adjustable in said slot, and means for clamping and holding the stem of said bearing, substantially as specified.

7. The combination with the machineframe, of a bracket, a cutter-axle mounted in bearings thereon, aguide-cutter on said axle, and a brace-ear on the bracket adapted to connect with the moldboard of an adjacent plow, substantially as specified.

In testimony that I claim the foregoing as my own I have hereto a'ffixed my signature in the presence of two witnesses.
